(54) PRINTED TEMPERATURE SENSOR


(57) A printed temperature sensor (10) comprising a substrate (1) with an electrical circuit (2) comprising a pair of electrodes (2a,2b) separated by an electrode gap (G). A sensor material (3) is disposed between the electrodes (2a,2b) to fill the electrode gap (G), wherein the sensor material (3) comprises semi-conducting micro-particles (3p) comprising an NTC material with a negative temperature coefficient (NTC), wherein the micro-particles(3p) are mixed in a dielectric matrix (3m) functioning as a binder for printing the sensor material (3); wherein the micro-particles (3p) contact each other to form an interconnected network through the dielectric matrix (3m), wherein the interconnected network of micro-particles (3p) acts as a conductive pathway with negative temperature coefficient between the electrodes (2a,2b).
